8 Claims. (Cl. 20-62) This invention relates to improvements in jalousie window construction, and more particularly to an improved pivot assembly for pivotally connecting the louvreor slat-retaining clips to the side members of the window frame. I

Conventionally, such retaining clips turn on pivot pins extending through aligned holes in the clips and frame side members, and it has been a special problem to assemble the clips to the pivot pins so that said clips seal tightly against the side members, as is necessary to prevent ingress of weather between louvre ends and frame. Stated broadly, an object of the present invention is to provide an effective yet simple solution of the aforesaid problem.

More particularly, the invention aims to provide a pivotal connection between the louvre-retaining clips and frame side members of a jalousie window, which eliminates the conventional pivot pin form of connection, while at the samev time connecting the clips to the frame members rotatably and without end play.

Another object of the invention is the provision of an improved retaining clip for the louvres of a jalousie window construction, characterized in that said clip incorporates as an integral part thereof its own pivot assembly for rotatably connecting same to the window frame side members. I j

Yet another object of the invention is the provision of a louvre-retaining clip incorporating a pivot assembly as aforesaid and which is further characterized by means for preventing unintentional Withdrawal of the clips from the side members of the window frame. V

Still another object of the inventionis the provision of a louvre-retaining clip having an integral pivot as aforesaid, wherein the pivot is in the form of a tongue or tab struck from the material of the clip body member, and wherein said pivot is so constructed and arranged as to receive a means, preferably in the form of a spring retaining ring, for securing the clip against accidental withdrawal from the window frame side members.

A still further object of the invention is the provision of a: louvre-end retaining clip pivot assembly and retaining ring combination for connecting the'louvres or slats of a jalousie window to the side members of the window frame, which is so constructed and arranged as to provide a simple yet thoroughly dependable'connection between said louvres and side members as well as to'prevent ingress of weather between the ends of the louvres and said side members. 7

The above and other objects and advantages of the improved louvre-retaining clip according to the invention will appear from the following detailed description thereof, in which reference is had to the accompanying drawings illustrating same, wherein:

'Fig. 1 is a side elevation of a portion ofa jalousie window construction, which illustrates ina general way the manner of connecting the louvres or slats thereof to the side members of the window through pivotally mounted louvre-retaining clips; s

and movement with respect to the window-frame side retaining rings according to the invention for securing the louvre-retaining clips against unintentional withdrawal from their associated side frame members to which they are pivotally connected, all said views illustrating the retaining rings engaged with the reduced neck portion of the clip pivots as herein proposed; and

Fig. 7 is a plan view, partly in section, depicting the action of a retaining ring of the form shown in Fig. 6 in preventing withdrawal of a clip pivot from itsassociated frame side member.

Referring to the drawings, and more particularly to Figs. 1 and 2, it is to be understood therefrom that the reference numeral 10 designates one side member of a jalousie window frame to which a plurality of louvre' retaining clips 11, 11a, etc. are pivotally connected. Said clips serve to mount the plurality of louvres or slats 12, 12a, etc. employed in jalousie window construction and, except for their pivot means, said retaining clips may be and preferably are similar to the retaining clips serving similar function disclosed in the Silvers Patent No. 2,640,233, dated June 2, 1953. More in detail, said clips 11, 11a, etc. each comprises an elongated body portion 13 provided with a louvre-backing. flange 14 and opposite.

louvre-retaining flanges 14a, 14b, the latter having a degree of resiliency whereby they secure the louvre end against the backing flange 14 with spring pressure. The body portions 13 of the clips are also formed with integral, laterally extending arms 15, 15a, etc. which are pivotally connected at their free ends as by rivets, or pins 16, 16a, etc. to a louvre-operating bar or rod 17 common to all said louvres.

Asv explained in the foregoing, prior louvre-retaining clips as aforesaid were connected to the side members of the window frame (corresponding to the aforesaid side member 10) by more or less conventional pivot pins extending through aligned holes in the clip body portion and the frame side member, and additionally spring means were required to insure weather-tight engagement between clip body portion and the adjacent side member. distinguished therefrom, retaining clips according to the invention are pivotally connected to the window-frame side member by a special pivot assembly which will now be described.

As heretofore, the frame side members 10 to which the improved retaining clips pivotally connect are provided with a plurality of holes 18 13a, etc. for receiving the pivots on which the clips turn. turning on conventional pivot pins formed separately therefrom, said clips are provided with integral pivots struck from the material of the clip body portions. 7 More particularly and as best seen in Fig. 3, said integral pivots take the form of right-angularly bent tabs generally designated 20 struck from the material of the clip body portion at approximately the junction of its clip-actuating arm (15, 15a, 15b, etc.) therewith. Preferably, said tabs 20 have rectangular outline and width between their parallel sides which is slightly less than the diameter of the side-member holes 18, 18a, etc. so that, when inserted in a hole, a tab may turn freely with respect to the side member,.while at the sametime having bearing on the edge-material of the side member which extends about and defines said hole. It will thus be seen that the invention provides pivot means integral with the louvre-end retainingclips providing for their pivotal connection to PatentedOct. 1, 1957 However, rather thanmembers, rather than pivot means formed separately from the retaining clips as heretofore employed.

According to a further feature of the invention, the clips 11, 110, etc. are positively secured against unintentional withdrawal from the frame side members 10 and, for this purpose, the tabs are provided with means for seating a spring retaining ring functioning in well known manner to prevent axial movement of one member (tab 20) rela tive to another (side frame 10). Illustratively, such means comprises aligned, oppositely facing U-notches 21, cut or otherwise formed in the side edges of each tab, said notches forming between them a narrow neck 23. Said notches and neck are of course capable of seating a spring retaining ring, to the same degree that a shaft groove, for exampleis adapted to seat such a ring.

Although according, to the invention any open retaining ring may be cooperated with a tab 20 to prevent unintentional axial withdrawal thereof from its side member hole 18 or 18a, etc., that is to say, any spring ring having a gap between its free ends large enough to enable said ring to be spread directly over the tab neck 23 by movement in the plane thereof, it is preferred to employ for this purpose a special retaining ring of one of the forms shown in Figs. 4-6, because such rings are by their design provided with means for preventing them from becoming accidentally disengaged from the tab following seating thereof in the tab groove as defined by the tabedge notches 21, 22 aforesaid. Thus, the retaining ring illustrated in Fig. 4 comprises an arcuate ring body 24 corresponding generally to a well known open retaining ring having substantially crescent shape, but the gap-forming free'ends 25a, 25b of said ring are specially constructed so that when properly engaged with a tab 20 they lock the ring thereto. For example, said ends have relatively long gap-forming edges 26a, 26b, and said edges are formed with oppositely facing U-notches 27a, 27b dimensioned to receive and resiliently embrace the narrow neck 23 of a tab along both its Side edges and along both its upper and under faces as well. Thus, when spread over the pivot tab 20 in the plane of the side edge notches 21, 22 thereof, a retaining ring as shown in Fig. 4 seats in the tab groove as defined by said notches 21, 22, and effectively locks to said narrowed neck portion with spring pressure.

In a retaining ring according to Fig. the gap-defining edges 28a, 28b, instead of being formed with U-notches, are instead provided with oppositely disposed L-shaped notches 29a, 29b, whose lower legs on sides 30a, 30b define upwardly facing hook-like formations adapted to resiliently hook under the narrow neck 23 of the tab 20. The ring is capable of exerting spring force on the opposite face of the tab through a tongue or lug 31 protruding inwardly from the inner periphery of the ring body at approximately its middle line or section. It will be understood that when spread over the narrow neck 23 of a tab 20 a retaining ring according to Fig. 5 not only spring-.

seats itself in the tab groove as defined by its side-edge notches 21, 22, but also it resiliently grips the neck along its side edges and along its upper and under faces also.

The retaining ring shown in Fig. 6 is an adaptation to the purposes of the present invention of the self-locking retaining ring disclosed and claimed in my Patent No. 2,755,698, dated July 24, 1956, in that it comprises an opemended ,arcuate ring body whose inner edge diameter and width of gap between its open ends correspond substantially to the width of the tab neck 23. The ring body ispreferably bowed about its vertical center line as shown and is further. characterized by triangular locking formations 32, 33 whichare struck from the material defining the gap-forming edges 34a, 34b of said ring and project from the convex face of thering. As seen in Fig. 7, when the Fig. 6 form of ring is assembled on a tab so that it seats in, the groove thereof defined by its side-edge notches 21, 22, and with its convex face and hence its locking projections 32, 33 facing forwardly or towardthe the retaining clip in direction as to draw it against the inner face of the frame side member 10, and also its locking projections hook beneath and lockingly engage with the relatively under face of the tab 20 slightly forwardly of the common plane of the tab notches 21, 22, thereby positively to lock said ring to the tab.

It is also within the purview of the invention to bow the Figs. 4 and 5 forms of retaining rings so that when assembled on their tabs they tend to draw the retaining clips against the inner face of the associated frame side member 10, as does the bowed ring of Fig. 6 as explained above. Also, if plane rings are employed, or if it is found that the bowed rings do not exert SlllllClCIlt force on the clips as to draw them tightly against said frame member, simple leaf springs (not shown) may be inserted between the louvre or slat ends and the body portions 13 of the retaining clips, such biasing the clips against the inner face of their associated side frame member, as is ormay be found desirable in providing the weather-tight joint therebetween.

Without further analysis, it will be seen that the retaining clip pivot assembly and the retaining ring form of locking means employed therewith according to the present invention achieves the desirable objectives therefor as explained in the foregoing. However, as many changes could be made in carrying out the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
